ArcPad
Good
o 8 years, 0 Failures
o Highly customized for geologic mapping
o Good staff/project uptake due to ease of use
o Self-contained, works offline
o GPSGate allows multiple applications to use a single GPS unit
o Transitioned FGS field mapping out of the dark ages of paper maps
Bad
o Developed by single staff member, doesn’t pass the ‘lottery test’
o Custom VB application
o Custom python toolbox for project & data management
o Existing GPS + GPSGate did not work with Windows 10 upgrade
o Shapefiles and lack of nulls creates data issues
o Many, many interlocking parts (VB code, python code, apl styles & forms, ArcMap style, etc.)
o Required data transformations in and out

Esri Collector for field mapping
o Completely customized applications built for individual project needs or broad use
o Accessibility across multiple platforms
o Plays nicely with organizational Esrienterprise accounts
o Compatible with most devices

Needs Assessment
Existing System (ArcPAD)
◦ High-resolution tracklog collection
◦ Access to prior fieldwork data
◦ ‘Quick drops’
◦ Offline access to data
◦ Staff attribution
New Features (Collector)
◦ Data compiled and saved within ArcOnline
◦ Data access anywhere on any device
◦ Downloadable basemaps
Must haves for the new field system
Coordination with IT Department & Implementation
◦ Intra-FDEP Cooperation▫ OTIS-GIS▫ FGS
◦ Documentation & implementation of existing, complicated data model
◦ Delay of development
• Custom backend code for tracklogs
• Custom backend code for merging
new data with pre-existing data
◦ Key Lessons
• Important to consider agency
restrictions
• Not all functionality is replicable
• Custom solutions require
development time
Hardware Testing
◦ Before testing could begin: GPS incompatibilities
• The ‘Bluetooth Only’ Problem
• Embedded GPS in tablets has a poor accuracy
• Bad Elf Pro - $599.99
• Accuracy
• Ease of Use
• Dependability
• Trimble R1 Unit - $2,200
• Accuracy
• Ease of Use
• Dependability
◦ Poor Collector documentation
◦ GPSGate failure
Online Platform
◦ Many features Wifi dependent▫ Basemaps▫ Pushing and pulling data
◦ Verizon Mifi▫ Data plan increased to account for overage
◦ Still not entirely dependable
◦ Failure when attempting to download offline maps
However, with a good Wifi connection…
◦ Back at the office, GIS users were able to:▫ Track field progress▫ Upload data to field teams▫ Edit and see data as it was being created
User Feedback
Good
◦ Accessible on any device – ‘grab and go’
◦ Share data between teams
◦ Ready to use▫ Pre-existing forms and data
translated well
◦ Trimble R1 was an excellent compliment to Collector
◦ Great basemaps (with Wifi)
◦ Bonus features when Wifi connection was available
Bad
◦ Offline mode unfunctional after tracklog customization
◦ Tracklog max acquisition rate: 30 seconds
◦ Lack of ‘quick drops’ resulted in frustration among staff
◦ BadElf had a very poor update rate and accuracy issues
◦ Add-ons greatly increased not only over all cost, but also beta testing
Final Verdict
◦ Collector performs best with a highly limited scope of development
◦ Don’t throw the ‘kitchen sink’ at it!
◦ Target limited functionality and break it into smaller, specific applications
◦ High cost of compatible Bluetooth GPS units requires additional funding for upgrades
◦ Unreliable offline maps
◦ Not good for navigation
◦ Works best with a wifi connection▫ Not reliable for remote fieldwork
◦ Still using ArcPAD
But..◦ Survey 123 was surprisingly underrated
◦ Helping to begin the process of organizing over 19,000 data points…
Survey 123
◦ Like Collector▫ Supports multiple users▫ Accessible across all devices▫ Nesting menus▫ “Works” on or offline
◦ Unlike Collector▫ Easily customizable▫ No need to get IT involved▫ No additional GPS hardware required▫ Easy for non-GIS users▫ No crashing▫ Dependable data uploads▫ Create vast amount of tabled data▫ Spatial component available
